    Display symbol version when dumping dynrelocs

    Both readelf/objdump know how to get symbol version string for dynamic
    symbols.  This patch extracts this functionality into a separate
    function and uses it to add symbol version string to versioned symbol
    names when dumping dynamic relocations.
